Introduction The Boari flap technique is a unique urinary tract reconstruction procedure performed after resection of the urinary tract. However, few previous reports have described the application of this technique to gastrointestinal cancer. Moreover, we have not found any papers describing the long-term prognosis. We report a case of right ureteral tract resection followed by Boari flap reconstruction for rectosigmoid carcinoma, with survival for 108 months without any urologic complications. Case presentation A woman in her 50s was diagnosed with rectosigmoid cancer by a local physician and referred to our institution. Computed tomography scans revealed right hydronephrosis caused by rectosigmoid cancer invasion at the lower two-thirds of the right ureter. During laparotomy, massive lymphatic infiltration from the primary lesion to right ureter was observed. After primary tumor resection with lower ureter excision, the Boari flap procedure was performed to reconstruct the ureteral deficit. The postoperative course was uneventful, and she was discharged on postoperative day 20. The patient has been seen every 4 months for 9 years with no recurrence or unpleasant symptoms. Discussion This technique is usually performed to manage specific conditions such as ureteral stenosis caused by ureteral calculi, retroperitoneal fibrosis, and gynecologic disorders. This procedure should be reconsidered as a possible option for gastrointestinal malignant cases instead of nephrostomy or cutaneous ureterostomy, given the low rate of complications and high patient satisfaction. Conclusion The Boari flap technique is particularly useful for bridging between the ureter and bladder in cases of colorectal malignancy with combined resection of the lower urinary tract.

A 74-year-old man visited our hospital complaining of abdominal pain. An abdominal computed tomography scan showed multiple wall thickness of the small bowel. Capsule endoscopy was recommended for further evaluation, and patency capsule examination was performed. Eighteen hours after patency capsule ingestion, he experienced small bowel perforation with severe peritonitis caused by intestinal pressure rising because of the patency capsule trapped in his terminal ileum. An ileocolic resection was performed, including the removal of the sclerotic ileum as an emergency surgery. A pathological examination showed transmural inflammation and multiple ulcers with perforation of the small intestine, consistent with Crohn’s disease. Here, we report a rare and valuable case of novel tag-less AgileTM patency capsule (Given Imaging Ltd., Yoqneam, Israel) retention leading to small bowel perforation.

In addition to the general surgical-site infection prevention measures in colorectal cancer surgery, we performed a simple subcutaneous scrubbing procedure with gauze at the time of abdominal closure, which reduced the incidence of wound infections. There are 289 patients whose primary colon cancer lesions were removed by elective surgeries. They were divided into Group A (74 patients with no wound infection prevention measures who were treated from 2002 to 2003), Group B (76 patients with wound infection prevention measures who were treated from 2007 to 2008), and Group C (139 patients with subcutaneous scrubbing with gauze plus the measures in Group B who were treated from 2009 to 2012). The incidence in Group A was 23%, while the corresponding values in Group B and Group C were 14.5% and 2.9%, respectively. The incidence of wound infections was substantially reduced by additional subcutaneous scrubbing with a saline solution and gauze during closure of a surgical incision. This very simple procedure was considered useful for surgical site infection prevention.

Background: Colorectal cancer most commonly metastasizes to the liver. However, in patients with liver metastases precluding radical resection, we still have no other choice but to

We report here a case of partial response to hepatic arterial infusion chemotherapy in a patient who developed serious hepatic failure due to unresectable colorectal cancer and hepatic metastasis and showed resistance to systemic chemotherapy with molecular targeted drugs, mFOLFOX6, and FOLFIRI. The patient was a 60-year-old woman who underwent sigmoidectomy for sigmoid colon cancer, lateral posterior hepatic segmentectomy for metastatic liver cancer, and postoperative radiation therapy for metastatic lung cancer. As first-line systemic chemotherapy, mFOLFOX6 (oxaliplatin, 5-fluorouracil, and leucovorin), bevacizumab + FOLFIRI (irinotecan, 5-fluorouracil, leucovorin), and anti-epidermal growth factor receptor antibody + irinotecan were administered, in that order. However, recurrent hepatic metastasis was exacerbated, which induced serious hepatic failure manifested by general malaise, jaundice, abnormal hepatic function, difficulty in walking due to bilateral lower extremity edema, and decreased appetite. The patient was admitted in a serious condition. After hospitalization, the patient received hepatic arterial infusion chemotherapy with 5-fluorouracil and l-leucovorin. After two complete courses, the symptoms improved. The patient’s performance status also improved, and she was discharged from the hospital. Four months after discharge, the patient had continued outpatient chemotherapy and maintained excellent performance status. Although HAIC is not presently considered an alternative to systemic chemotherapy, it is sometimes effective in patients who show resistance to molecular targeted drug therapy, FOLFOX, and FOLFIRI, and in whom hepatic metastasis is a key factor in determining prognosis and serious hepatic failure. Further studies should be performed in the future to verify these findings.

Although appendiceal anatomical anomalies are very rare, understanding of the anatomical details of these anomalies is important for surgery. In this case report, we present images from multi-detector row computed tomography (MDCT) and histological findings of a rare anatomical appendiceal anomaly originating from the cecum and opening into the terminal ileum like a bridge. These anatomical details were clearly depicted on MDCT with multi-planar reconstruction. MDCT demonstrated a communication between the appendix and terminal ileum. Histological analysis revealed that a normal mucosal layer was maintained from the appendix to the connected ileum, without any evidence of inflammatory or neoplastic changes, and only thickening of the muscular layer of the appendix was identified. Based on these histological findings, the appendix was considered to represent an anatomical anomaly rather than secondary fistula caused by inflammation or neoplasm, which has not yet been reported.
